LoL: Conviction vs Winthrop University (BO3) - North American Challengers League Group Stage

Platform comparison

Market context

Conviction’s BO3 against Winthrop University sits in a familiar NACL pattern: the match-up has shown relatively tight recent scoring, but the pre-match price still leans clearly towards Conviction. Sheep Esports’ season page lists Conviction on 3 wins to Winthrop University’s 2, with five games played in the series context shown there, while bookmaker aggregates on EGamersWorld make Conviction a solid favourite at around 1.35 to 1.36 decimal, with Winthrop closer to 2.89.[2][4] That implies a rough mid-70s win chance for Conviction, which is notably stronger than the market’s current 0% YES on the contract, suggesting either a stale price, a misunderstanding of the contract condition, or that traders are not pricing the underlying match winner at all.[4][5]

The main catalyst is simple: confirmation of whether the scheduled series is actually played and whether the correct match outcome is the settlement driver, because prediction contracts in this ecosystem can diverge sharply from sportsbook moneylines when the wording is unusual.[1][3] Here, the Polymarket listing itself appears tied to a different Game 3 Baron Nashor condition, not a straightforward match winner, so traders need to watch for any schedule changes, result reporting, or contract-description mismatch before the settlement window closes.[1][3] If the series is delayed beyond the seven-day allowance or not played, the market would resolve 50-50 rather than to either team, which is particularly relevant when a 0% quote sits alongside an active esports fixture.[1]

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). That keeps the comparison honest — a single canonical probability across the row, with the venue-by-venue trade-offs spelt out in the columns next to it.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.

FAQ

How does resolution work?

Through the UMA Optimistic Oracle on Polygon: a proposer submits the outcome, a two-hour challenge window opens, and USDC payouts settle automatically once the result is final.

What's the difference between YES and NO shares?

A YES share pays $1.00 if the event happens, $0 otherwise. A NO share pays $1.00 if the event doesn't happen. The market price between 0¢ and 100¢ is the implied probability.

What does Polymarket cost to trade?

Polymarket itself charges 0% — the only cost is the Polygon network fee, typically under $0.01 per transaction. Off-chain venues like Kalshi or Betfair charge 2-7% commission.

How fast are USDC deposits?

Polygon credits deposits after 12 confirmations — usually under 30 seconds. Withdrawals follow the same path and land back in your wallet within minutes.

How reliable are the quoted odds?

The YES/NO percentages are the live mid-prices of the Polymarket order book. On deep markets they move every few seconds; on thinner ones you'll see short plateaus.
